Euura imperfecta ZMUO.

296 Euura imperfecta (Zaddach, 1876) Figs 311, 535 Nematus imperfectus Zaddach, 1876: 73, 80–81. Syntypes ♀♀, probably destroyed (Blank & Taeger 1998). Type localities: Germany, Finland, Scotland and Poland. Pachynematus imperfectus var. claristernis Enslin, 1916a: 484. Lectotype designated below. Synonymy by Taeger et al. (2010). Pachynematus (Larinematus) tatricus Roller & Haris, 2008: 47–49. Syn. nov. Diagnosis Small subapical tooth of claws, colouration (male largely black; in female, pterostigma basally paler than apically, abdomen dorsally black, metafemur at least partly pale), structure of valvula 3 (in dorsal view rather broad, not tapering, and posteriorly with invagination) and penis valve enable separation of the species from the other Euura. The shape of valvula 3 varies somewhat, but there is no clear gap in variability and apparently no correlation with variability in mesepisternum colouration (from completely black to completely pale). Type material examined Lectotype Pachynematus imperfectus var. claristernis, here designated GERMANY – Mecklenburg-Vorpommern • ♀; Teschendorf in Mecklenburg; 53.45° N, 13.36° E; 11 Apr. 1896; F.W. Konow leg.; ZSM, GBIF-GISHym3221. Holotype Pachynematus (Larinematus) tatricus SLOVAKIA – High Tatra • ♀; Tatranská Lomnica, Štart; 49.179° N, 20.255° E; 1150 m a.s.l.; 15 May 2007; O. Majzlan leg.; SNMC. Notes Photos examined. Host plants Larix spp. Genetics COI Based on 5 specimens, maximum within-species distance is 2.28% and the nearest neighbour, diverging by a minimum of 5.78%, is Euura hulteni. Nuclear Based on 3 specimens, maximum within-species distance is 1.2% (0.31% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 2.87%, is Euura villosa. Distribution and material examined Palaearctic. Specimens studied are from Austria, Finland, Germany, and Russia.
